Respiratory System Flashcards
You have already examined the ________, the external portion of the rabbit’s nose.
nares
Rabbits are obligate __________; a rabbit cannot breathe through its mouth due to the position of the glottis and epiglottis.
nasal breathers
The __________, a cartilaginous structure, protects the entrance to the trachea and is important in vocalization.
larynx
glottis and epiglottis as the opening of the respiratory system from the ____________, the area just posterior to the mouth and common to both the respiratory and digestive systems.
pharynx
pathway from nares to trachea
From the nares, air travels to the pharynx, past the glottis and epiglottis, to the larynx, and then the trachea.
Posterior to the larynx is the _____________. The _________ is a long tube ringed with bands of cartilage that provide support and prevent collapse.
trachea
The trachea continues posteriorly until it divides into left and right. __________ dorsal to the heart. These _____ lead to the left and right lungs.
bronchi
bronchi branch further into smaller ________, which terminate in vestibules containing alveoli,
bronchioles
where most gas exchange occurs.
alveoli
The lungs of the rabbit are divided into three portions:
the anterior, middle, and posterior lobes.
Due to the position of the heart on the left side of the cavity, the left anterior lobe is much ______________ than its counterpart on the right.
smaller
Long tube reinforced with cartilaginous rings to prevent collapse under negative pressures generated during inhalation
TRACHEA
Enlarged oval protrusion toward the cranial end of trachea Aka Voice Box
LARYNX
Division of the trachea before going to the lungs
BRONCHI
Divided into 4 lobes (cranial, medial, caudal and accessory) Divided into 2 lobes (cranial and caudal)
RIGHT LUNG
